Platypus Wiki is an enhanced Wiki Wiki Web with ideas taken from Semantic Web. We call it a Semantic Wiki Wiki Web. It offers a simple user interface to create a Wiki Page plus metadata according with W3C standards. It uses RDF (Resource Description Framework), RDF Schema, and OWL (Web Ontology Language) to create ontologies and manage metadata.
Platypus Wiki is an ongoing project started on 23th December 2003. We distribute a pre-alpha version to test the concept and have a feedback from some earlier users. If you want to try it, read the download section to find how you can get it and the installation section to install and run it.
The pre-alpha version is again in early stage of development and implements only few features, but you can already try it and see how it works.

* Full support of the JBoss Portal 2.0 security constructs to allow users and roles to be associated with editing and display of wiki pages and attachments within the context of a JSR 168 compliant portal.
* Full support of wiki page histories and rollback.
* An integrated DIFF tool.
* A Plugin framework which allows different wiki types to be defined and associated with different plugin stacks which add contextual content to wiki pages or do translations.
* Full support for attachments (attachment histories are pending).
* Currently supports the JSPWiki wikitext syntax.
* Includes a prototype search engine.
* Simple URL support even while running within JBoss Portal so users can access wikipages by the URL pattern: http://host/wiki/PageName

Elsie is a wiki engine written in Java. It supports most popular wiki features including wiki markup syntax, content management (view, edit, attachment..), version control (history, diff, revert..), access control list, etc. Elsie implements an IoC-based wiki kernel, which loads service providers and wiki action plug-ins dynamically during runtime. Elsie also offers a clearly-defined, servlet-independent wiki API set via which a wiki may be extended and customized easily.

JAMWiki is a Wiki engine implemented using Java/JSP that attempts to provide much of the functionality of MediaWiki. It can be run with or without a database and is designed to be fast and easy to set up.
